Founded in 1980, Gongyi Filter Industry Co., Ltd., formerly known as Gongyi Qingfeng Filter Media Factory, is one of the earliest manufacturers of polyaluminum chloride (PAC) in China. In 1997, it underwent restructuring and renaming, laying the foundation for its market-oriented and group-based development. With over forty years of dedicated experience, we have grown into a significant force in China’s water treatment materials manufacturing industry, and are a comprehensive chemical and filter media supplier with widespread influence within the industry.

As a participant in the formulation of China’s national standard for polyaluminum chloride, the company holds a leading position in China in terms of technological research and development, product quality, and industry standardization. We have built a complete water treatment chemical manufacturing system, with products covering PAC, PAM, ACH, PFS, aluminum sulfate, calcium chloride, ferrous sulfate, glucose, activated carbon, quartz sand, and various filter media, forming a comprehensive product matrix to meet the needs of multiple industries, including industrial water treatment, municipal waterworks, environmental engineering, food processing, papermaking, and mining.

Currently, the company has six major production bases in Shanxi, Hubei, Qinghai, Xinjiang, Xingyang, and Gongyi, possessing a strong manufacturing scale, a stable supply chain system, and strict quality control capabilities. We have obtained ISO9001, ISO14001, and ISO45001 forming a comprehensive quality and process management system covering R&D, production, and logistics.

Relying on strong production capacity, high quality, and robust R&D, our products are exported to many countries and regions in Southeast Asia, the Middle East, Europe, the Americas, and South Asia. With a strategic positioning as a “provider of high-quality water treatment solutions,” the company is committed to driving industry upgrades through technological innovation, protecting global clean water sources with reliable products, and showcasing the strength and quality of Chinese water treatment materials to the world.
